Diffuse pulmonary ossification is a rare condition. We examined three cases of it in Japan, and attempted histochemically to stain for deposition of aluminum and iron in bony tissues. The patients were all female, and in their mid-twenties, mid- eighties, and later teen years. One of the patients had been exposed to heavy metals in her work involving heavy-metal analyses for 18 months. Aluminum...

The localized corrosion behavior of a galvanic aluminum copper couple was investigated by in situ fluorescence imaging with a fiber-optic imaging sensor. Three different, but complementary methods were used for visualizing remote corrosion sites, mapping the topography of the metal surface, and measuring local chemical concentrations of H+, OH-, and Al3+. The first method is based on a pH-sensi...

Aluminum-containing adjuvants are widely used in preventive vaccines against infectious diseases and in preparations for allergy immunotherapy. The mechanism by which they enhance the immune response remains poorly understood. Aluminum adjuvants selectively stimulate a Th2 immune response upon injection of mice and a mixed response in human beings. They support activation of CD8 T cells, but th...

A new dealkylation reaction between organophosphate esters and Salen aluminum bromide compounds has been used to prepare three new aluminum salen compounds salen((t)Bu)AlOP(O)Ph2 (1) (salen = N,N'-ethylenebis(3,5-di-tert-butylsalicylideneimine)), [(MeOH)Alsalen((t)Bu)[OMePO2(O)]Alsalen((t)Bu)[OMePO2(O)]Alsalen((t)Bu)]Br (2), and [salpen((t)Bu)AlO]2[(BuO)2PO]2 (3) (salpen = N,N'-propylenebis(3,5...

Reduction in size and weight of micro-electronic devices becomes limited by the availability of suitable power sources. This paper presents micro-fabrication routes of an aluminum anode/oxygenated alkaline electrolyte/platinum cathode micro cell as a first step towards the development of highly efficient thin form factor aluminum anode cells. On-demand microfluidic addition of electrolyte can o...

A sensitive and accurate method for the spectrofluorimetric determination of trace levels of aluminum in hemodialysis solutions using Mordant Red 19 as the complexation reagent has been developed. The optimal experimental conditions for the concentration of fluorimetric reagent, pH, temperature, and the specific type of matrix are reported. The emission of the fluorescent metal chelate was meas...

A reversible photo-driven sensor for aluminum ions based on photochromicspiropyran was reported with rapid response time. The detection of aluminum wasperformed via the chelation of aluminum ions with the merocyanine form (MC) ofphotochromic spiropyran. ¹H NMR studies confirmed the conversation from the MC forminto the Al3+ -MC form. Addition of aluminum ions to the spiropyran (SP) in a MeCN/H₂...

The study reported in the present issue of the Journal of Alzheimer’s disease by Mizoroki et al. [8] concludes that the failure of treatment of transgenic mice with aluminum maltolate to induce Alzheimer’s-like neuropathological changes provides proof that aluminum is not a causative agent in the etiology of Alzheimer’s disease. In our opinion, this report by Mizoroki et al. fails to provide an...

: In this work, we have proposed a concept for the generation of three-dimensional (3D) nanostructured metal alloys of immiscible materials induced by megahertz-frequency ultrafast laser pulses. A mixture of two microparticle materials (aluminum and nickel oxide) and nickel oxide microparticles coated onto an aluminum foil have been used in this study. After laser irradiation, three different t...

Although chronic aluminum neurotoxicity has been well established, the mechanism of the toxicity has not been elucidated yet. In order to simplify the study of the aluminum neurotoxicity, we employed the pulse exposure of cultured rat cortical neurons to 250 microM aluminum-maltol for 1 h at the early stage (6 h after plating), which resulted in abnormal distribution of neurofilament L (NFL) an...
